In December 2013, 24 units of CANNY Super-high heavy-duty public traffic type escalators installed in the Mt. Tianmen Tunnel of Zhangjiajie were officially delivered, which attracted worldwide attention and brought significant economic and social benefits to the scenic spot. A few days ago, CANNY once again provided 4 heavy-duty public traffic type escalators with the height of 21.5 meters for the Mt. Tianmen Scenic Area, further enhancing the visitor experience.
